------
Animal Equation:: o + c = 35 animals
Leg Equation::: 4o + 2c = 114
--------------------------------------
Modify for elimination::
o + c = 35
2o + c = 57
---------------
Subtract and solve for "o"::
o = 22 (# of cows)
-----
Solve for "c":
o + c = 35
c = 35-22 = 13 (# of chickens)
--------------
